' WATER-PRESSURE PISTON-ENGINE Specification of Letters Patent.

Patented July 16, 19.07.

Application filed April 12, 1907. Serial No. 367,894.

To all whom it may concern;

Be it known that I, HENRY B. MEIER, a citizen of the United States, and a resident of New York, countyand State of New York, have invented certain new and usei'ul Improvements in Water-Pressure Piston-Engines,

- of which the following isa'specification.

vers m, m. The latter are rigidly connected with the The present invention pertains to water pressure piston engines, particularly to such that are used to operate pipe organs,,and has for its object to provide a con,-v struction that will allow a full and quick valve opening at the commencement of the stroke, and by giving the piston a full pressure at the start, the wire drawing of the power medium in the ports of the engine and valve ton engines, is that the small ports of the auxiliary valve become easily clogged by foreign matters the water, such as grease, straw; etc.

contained in My invention consists in the combination of'a water pressure piston engine having a single piston valve witha device that-at the end of the piston stroke will forcibly move the valve to rapidly open the ports of the cylinder to allow of a full pressure for the co1n1nencement of the new stroke.

Inorder to make my invention more clear, the same is illustrated in the accompanying drawing, in which similar reference letters denote corresponding parts, and in which Figures 1 and 'Zare longitudinal sections through the engine illustrating the operation of my device, and Fig;

Bis a top plan view thereof.

In the drawings denotes the cylinder, bthe piston working therein, a the valve casing, d the valve, and

e, e the ports leading from the valve casing into the cylinder.

9 denotes the valve rod, and h the piston rod. To one end of the latter, an arm f is rigidly secured, which is formed with a sleeve'i to loosely engage the valve rod 9, and to slide thereon during the backward and forward movement of the piston between two adjustable stops or-collars j, j. .lournaled in a bracket projecting from the cylinder is a rocking shaft [that extends transversely to the valve rod, and that carries bifurcated lerocking shaft 1 and are each to embrace a pin or projection in extending laterally from the sides of the valve rod g. Secured to each end of said shaft is also a crank n, the free end of which is connected at p with'a coil spring 0 that at p is attached to the cylinder 11.

The valve d is provided with a bore q that isrednced at its outer end and adapted to receive the lowerend of the valve rod 9. By means of a collar 7" the rod isprev ented from disengaging the valve, but allowed. to slide up and down in the wider portion of the bore. The latter must be of such a depth that when the arm f of the piston rod h forces the valve rod forwarder backi G 5 against the tension of their springs o, o y from their inward and moves the .ers m, mswinging the cranks clined left or right position (Fig. 1) toward and intd the central or vertical position (Fig. 2), the end .of the valve rod will freely slidewithin the bore q without moving the valve. Upon further movement of the piston rod and of the valve rod,'the latter will strike the inner end N -v of the bore q while at the same time the cranks will be swung out-of their vertical or central position to be instantaneously and forcibly drawn by the springs 0', 0 to the farthest end of their swinging movement. Thereby the levers m, m cause the valve rod to rapidly move the valve so as to entirely open the port a at the end of the corresponding stroke of the piston; It is evident, that the same valve motion can be used with engines driven by any other fluid pressure,,as compressed air, steam, etc.

What I claim desire to secureby Letters Pat ent is:

1 In a fluid pressure piston engine, the combination with a single piston valve, the latter having a longitudinal bore, of a valve rod slidably engaging said bore and connected with said valve, means to impart a preliminary movement to the said'valve rod, a spring actuated rocking shaft. supported from theeugine and extending trans versely thereto, bifurcated levers rigidly secured to said rocking shaftnnd projections on he valve rod engaged by said bifurcated levers, substantially asand for the purpose specified.

2. In a fluid pressure piston engine, the combination with a single piston valve, the latter having a longitudinal bore, of a valve rod slidably. engaging said'bore and connected with the valve, the piston rod operating said valve rod. a rocking shaft supported from'the engine and jextending transversely thereto, cranks, secured to said rocking shaft, coil springs secured to ,the engine and connected .with said cranks, bifurcated. arms rigidly se-' cured to said rocking shaft and projections on the valve rod engaged by said levers; substantially as and for the purpose specified.
